Salehi stressed that it was time for foreign troops to leave Iraq and for the country to move closer to its neighbors in Syria, Turkey and Iran, the semiofficial Fars News Agency reports.

His visit coincided with the return of radical Shiite cleric Moqtada Sadr, who seemingly ended his self-imposed exile in Iran with a family visit in the Iraqi holy city of Najaf.

Sadr was in the cross hairs of U.S. military forces before he fled Iraq to pursue cleric studies in Iran in 2007. His political party in Iraq helped secure a second term for Iraqi Prime Minister Nouri al-Maliki after the Iraqi leader paid a November visit to Iran.

P.J. Crowley, a spokesman for the U.S. State Department, said during his regular briefing that Sadr was Iraq's problem now.

"Sadr is the leader of an Iraqi political party that won a number of seats in the March 2010 election and his return is a matter between him and the government of Iraq," he said.
